采用水模型实验模拟了钢包钢水中微小相去除夹杂物的现象,利用高速摄像仪和图像处理技术分析了小气泡和夹杂物模拟物的运动行为,并且进行了净化剂和3种制球方式去除夹杂模拟物的实验,分析了气泡发生方式去除夹杂物的效果和原因,以提高钢水洁净度。结果表明:加入净化剂后,促进了夹杂物的去除,发现了气泡捕获多个夹杂模拟物的现象。在不同时刻,夹杂模拟物的去除率比没有产生小气泡时的去除率要高,平均提高13.66%。在3种气泡发生方式中,由于气泡生成时对内核材料的冲击作用,促进了净化剂的裂解,使得以外层净化剂加内核模拟物方式形成的复合球体最容易产生小气泡,夹杂物去除率100%,效果最好。
The water model experiment was used to simulate the removal of inclusions by the tiny phase in the ladle molten steel. The movement of small bubbles and inclusion simulants was analyzed by high-speed camera and image processing technology. The removal of the scavenger and the three ball-making methods Inclusion of mimic experiments, analysis of the bubble generation effect of removing inclusions and the reasons for improving the cleanliness of molten steel. The results show that the removal of inclusions is facilitated by the addition of scavenger, and the phenomenon of bubbles trapped by many entrained mimics has been found. At different times, the removal rates of inclusions mimics are higher than those without bubbles, an average increase of 13.66%. In the three bubble generation modes, the cracking of the scavenger is promoted due to the impact of the bubble generation on the inner core material, so that the composite sphere formed by the outer scavenger and the core simulation is most likely to generate small bubbles, and the inclusion removal rate 100%, the best effect.
